I would like to know if there is easy, cheap and straightforward way to determined removal rate of pollutants by nanoparticles?
I prepared several types of nanoparticles, (bare, polymer coated, bimetallic, carbon coated) and need to check absorption of heavy metals under different conditions (pH, Temp., presence of electrolytes and other pollutants, reusability, weak magnetic force) I know that Isothermal Calorimetric titration is option with polymer coated, but I was wondering, if there is any other in situ technique ( either electrochemical or optical) to measure amount of absorbed heavy metals and released or free heavy metal ions?
Dear Stefan
For heavy metal, try to use atomic absorption spectroscopy, select the metal that you want to measure its rate of removal from wastewater. But this method is ex-situ
Regards,
I think that method cannot differentiate between free and bound forms
Stafen,
Sure this method cant differentiate between them but you will measure the rate of removal of heavy metal form the wastewater which in turn will be either mounted on the adsorbent or disappeared by any other way from the ionic form in the wastewater. In other words the free ionic metals will let you know the bounded one. We did this to detect Cu, and Hg in wastewater.
Regards,
